TOOL FOR MOUNTING DISK -WHEELS.

My invention relates to an improved tool for mounting disk wheels.

According to the present pract1ce, in con: nection with disk wheels of the Allelic-hi1" type, two tools are employed for mounting the wheel on the hub. A pilot bar is used to guide the wheel to its place on the hub and a socket wrench is used to screw up the nuts which hold the wheel on the hub. after the wheel has been guided to position by the pilot bar. l

The chief object of my invention is to provide a single tool which will serve both as a pilot bar to guide the wheel to position and as a socket Wrench to turn the nuts screwed on the studs of the hub and supporting the wheel.

Further objects, and objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow. My nvention is clearly defined and pointed out in the appended claims. A structure constituting a preferred embodiment of my invention is illustrated in the accompanying drawing, forming a part of this specification, in WhiCllI- Fig. 1 is a plan view of a tool embodying my invention;

Fig. 2 is a fragmentary end view on an enlarged scale showing the wrench socket;

Fig. 3 is a detail sectional view take-non line 3 -3 of Fig. 1, looking in the direction of the arrows;

Fig. 4 is a vertical sectional view through a disk wheel showing the use of my tool for guiding the wheel to position; and

Fig. 5 is a side elevation of one of the nuts for holding the wheel on the hub.

In the drawing, the same reference numerals refer to the same parts throughout the several views. 5

The embodiment of my invention which is shown in the drawings comprises a rod or bar 10, which is bent upon itself at 11 to form the portion 12 extending back alongside the bar for about half its length, where it is bent at about right angles to form the lateral extension 13 extending perpendicularly to the bar 10. The. parts 10 and 12 together form a grip or handle by which the tool may be manipulated very con veniently. A head 14. is provided on the free end of the portion 13. said head having a polygonal socket 15 adapted to lit. the heads of the holding nuts for the wheel. A flange 16 extends from one edge of the free end of the bar 10. said flange being transversely curved as shown in Fig. 3.

A disk wheclof the Michelin type comprises a hub 21 having an annular flange 17 which carries a plurality of threaded studs 18. The wheel proper is constituted by a wheel. disk 19, to the periphery of which the tire rim is fastened. The disk has a central opening through which the hub extends and 'a plurality of perforated sockets 20 adjacent said central opening, through which the threaded studs 18 extend. The wheel disk is retained on the hub by nuts, such as shown in Fig. 5, screwed on the threaded studs 18, and each provided with a conical nose 21 engaging in the socket 20, and a polygonal head 22.

In Fig. 4, a tool constructed in accordance with my invention is shown in position for guiding the wheel to its place on the hub 21. The bar 10 isinserted through one of the perforated sockets 20, and the curved flange 16 at the end of the bar fulcrums on the corresponding Stud 18. The operator grasps the tool by the handle formed by the part 12 and lifts. The tool acts as a lever of the second class and the disk 19 is lifted until it can he slid down the bar 10 to its place on the hub. The projecting part 13 of the tool which carries the socket wrench H prevents the wheel sliding down upon the bar and pinching the hand of the operator or otherwise interfering with his manipulation. The bar guides the disk so that the perforated socket through which the bar extends, engages the stud 18 on which the bar is fulcrumed. This movement brings the disk to position with the studs 18 extending through the corresponding perforated sockets 20. The bar is then removed and the holding nuts screwed on the studs 18. The socket 15 of the tool fits the heads 22 of the holding nuts, and the operator, by grasping the handle 12 and the free end of the bar 10 to rotate the tool around the axis of part 13, secures a mechanical advantage by means of which a considerable force may be applied to screw up the holding nuts.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A pilot bar for lifting den'iountable disk wheels into place having one end shaped to fit and fulcrum on a part of a wheel hub of usual construction, and a projection laterally of the body of the bar intermediate its ends whereby when the tool is used as a pilot bar, the wheel may not sli on the bar downwardly beyond the pr0 ecti0n when the bar occupies an inclined position.

2. A device of the class described comprising a bar having a transversely curved flange extending longitudinally from one edge of one end thereof, said flange forming a seat p oviding a fulcrum engagement with a wheel hub, and a projection laterally of the body of the bar intermediate its ends, whereby when the tool is we as a pilot bar, the wheel may not slip on the bar downwardly beyond the projection when the bar occupies an inclined position.

3. A tool of the class described mmprising a bar shaped at one end to fulcrum on a wheel hub part, the opposite end of said bar forming a manipulatory handle when the tool is used as a pilot bar, and means intermediate said ends to limit the movement of the wheel toward the handle when the handle is depressed below the horizontal.

In testimony whereof, I a tlix my signature.
